Music Crab-Learn to read music

I have played organ/piano for over four years now, I am mostly self taught. Site reading I have always ignored learning because of my dyslexia and ADHD I thought it would be too difficult for me to do. Interaction with games is how I have learned the best in the past. This game is good example of how I hope the future of learning will become, through interactive experiences rather then just abstract concepts. Thank you for helping me unlock my learning potential.

Just discovered this game in my attempts to improve my sight reading in a fun way. I love the concept and the layout, but there is work to be done. For starters, I am not sure how to advance through all the levels. I made it through round 7/level 26, have plenty of shells (although as one other review mentioned how shells are awarded is confusing too) but no more levels appear for me to select or unlock. I thought there were supposed to be hundreds of levels? How am I supposed to access them? If they are an in app purchase there are no prompts. I think an instructions or demo screen would be useful as well.

I liked the crab run game, it exposes you to different keyboards in a universal way. The game demands sometimes more hand eye coordination that practice reading but it still helps. I wish more levels were unlocked and the fish swimming in the background sometimes distract but overall creative idea.
